Key Design Patterns¶
- Context API: Global state management
- Custom Hooks: Code reuse
- Compound Components: Flexible UI
- Container/Presenter: Separation of concerns
Performance Optimization¶
- Lazy loading screens
- Memoization with React.memo
- useCallback for event handlers
- Image caching
State Management¶
// AuthContext
const AuthContext = React.createContext<{
user: User | null;
token: string | null;
login(): Promise<void>;
logout(): Promise<void>;
}>(null);
